How do you calculate hydraulic cylinder force from pressure and bore?

Cylinder force (F in N) equals hydraulic pressure (P in Pascals) multiplied by the piston cross-sectional area (A = π × r² in m²): F = P × A. For a 100mm (0.1m) bore cylinder operating at 200 bar (20,000,000 Pa), force = 20,000,000 × (π × 0.05²) = 157,080 N ≈ 157.1 kN (35,314 lbf or 16.0 metric tons).

What is the formula to convert PSI to cylinder clamp force?

Force in pounds (lbf) = Pressure (PSI) × Area (square inches). A 4-inch bore cylinder has an area of π × 2² ≈ 12.57 in². At 3,000 PSI hydraulic pressure, force = 3,000 × 12.57 = 37,710 lbf (18.85 US tons).

How to Convert Square Decimeter to Square Dekameter

Converting Square Decimeter (dm²) to Square Dekameter (dam²) is a core calculation in Surface Area, which measures the two-dimensional extent of a surface, planar boundary, or land parcel. Both units reside within the International System of Units (SI) and share an identical physical dimension vector ([L²]), separated strictly by a decimal order-of-magnitude factor (10^-4). Because this shift involves integer powers of 10, the conversion is mathematically exact and free from decimal rounding or irrational fractional loss. Exactly 1 Square Decimeter equals 0.0001 Square Dekameter.

1 Square Dekameter is larger than 1 Square Decimeter. Specifically, 1 Square Decimeter equals 0.0001 square dekameters, meaning 1 Square Dekameter is 10000 times larger than 1 Square Decimeter (a difference of 4.00 orders of magnitude). Expressing measurements in square decimeters requires a larger numerical value to represent the equivalent physical magnitude.

A typical standard square ceramic wall mosaic tile surface area (100 cm²) measures 1 dm², which corresponds to 0.0001 Square Dekameter (Square Dekameter).

One Square Decimeter is equivalent to 0.0001 Square Dekameters. The exact mathematical relation is 1 dm² = 0.0001 dam².

To convert an area from Square Decimeters to Square Dekameters, multiply by 0.0001. The equation is V(dam²) = V(dm²) × 0.0001.

To convert from Square Dekameters to Square Decimeters, multiply the value by 10000. The inverse formula is V(dm²) = V(dam²) × 10000.

A square dekameter (dam²) is equivalent to 100 square meters. It is also known as an 'are' (a) and is used in European land registration and real estate metrics for calculating property and plot sizes.
